HARRY SMITH, OF MOUNT VERNON, TEXAS.

CAR-DOOR.

rsareeo.

Application filed May 3, 1913.

To all whom it may concern:

Be it known that I, HARRY SMITH, a citizen of the United States, residing at Mt. Vernon, in the county of Franklin and State of Texas, have invented a new and useful Car-Door, of which the following is a specification.

This application discloses matter divided out of my co-pending application No. 7275133 filled October 23, 1912.

One object of the present invention is to provide means for mounting a barrier in such a manner that the same, when moved, will be elevated. Another object of the invention is to provide a means whereby the barrier, when moved, will be lifted at its forward edge, when its rear edge is lifted, and thereby preventing a binding of the barrier, as the same is moved.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made with in the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 shows the invention in side elevation;

Fig. 2 is a horizontal section;

Fig. 3 is a section on the line 33 of Fig. 1;

Fig. 4 is a section 011 the line H of Fig. 1; and

Fig. 5 is a diagrammatic view, showing the door in closed position.

In carrying out the invention there is provided a supporting structure which, in the present instance, although not necessarily, is the wall 1 of a railway vehicle, the wall 1 having a door way 2. Projecting from the wall 1 adjacent the forward edge of the door way 2 is a jamb 3 supporting one end of an upper track 4 and one end of a lower track 5, the tracks at and 5 being supported, intermediate their ends by bolts 6 or the like which are connected to the wall 1. The rear ends of the tracks 4 and 5, however, are free to have a vertical movement. The ends 7 of the tracks AL and 5 are received in vertical slots 8 formed in keepers 9 which are secured to the wall 1 of thecar. From the foregoing it will be seen that although Specification of Letters Patent.

Patented July 3, 191?.

Serial No. 765,408.

the keepers 9 permit the free ends 7 of the tracks a and 5 to have a vertical movement, the keepers 9, nevertheless constitute means for preventing the free ends 7 of the tracks 1 and 5 from having a horizontal movement.

The door for the doorway 2 is indicated generally by the numeral 10 and may be of any desired construction. Along its lower edge, the door 10 is beveled as indicated at 11, so as torelease its hold upon the sill 12, as soon as the door is raised, by mechanism to be described hereinafter.

Along the forward edge of the door 10 extends a style 14, terminating in hooks 15 which extend around the tracks at and 5. Another stile 16 is applied to the rear edge of the door 10. Cross bar 17 extend transversely of the door 10 adjacent its upper and lower ends, the cross bars 17 terminating in off set hooks 18 engaging the tracks 1 and 5.

The upper cross bar 17 is provided with spaced loops 19 and 20. Mounted in the loop 19 and in the door 10 is a shaft 21, and mounted in the loop 20 and in the door 10 is a shaft 22. T couplings 23 are mounted to swing upon the shafts 21 and 22. One T coupling is connected with a straight, rigid member 24, the lower end of which is received in a head 25 which is journaled in a bracket 26 secured to the lower portion of the wall 1. The other T coupling 23 receives the upper end of the rigid member 27, provided with a rectangularly disposed extension 28, a coupling 29 being employed, if desired, for connecting the parts 27 and 28. The extremity of the extension 28 is received in a head 31 supported for pivotal movement in a bracket 30, similar to the bracket 26 and secured to the wall 1 of the car.

When the door 10 is in open position as shown in Fig. 1, the door will be supported by the engagement between the hooks 15 and 18 and the upper track 4, engagement between the lower hooks 15 and 18 and the track 5 serving to prevent the door 10 from swinging transversely. Then the door is in an open position as above described, the extension 28 of the rigid member 27 lies in an out of the way position, below the sill of the doorway 2.

In order to close the door, the same is pushed toward the amb 3. Under such circumstances, the door will be lifted bodily, and will swing into the position indicated diagrammatically on Fig. 4:, under which circumstances, the upper hooks 15 and 18 will come again into engagement with the upper track 4.

It will be understood that the structure herein disclosed is adapted to be used upon the doors of stock cars, box cars, heavy gates, warehouse doors, and elsewhere, in locations in which a structure of the type herein disclosed may be desired.

Having thus described the invention, what is claimed is In a device of the class described, a car having a doorway; upper and lower hori- Zontal bars secured to the car in spaced relation thereto and located above and below the doorway; a door for the doorway; a vertical strip secured to the forward edge of the door and terminating in hooks engaged with the upper and lower bars; upper and lower horizontal strips secured to the door adjacent its upper and lower edges, the upper strip having spaced outwardly projecting loops located adjacent the forward and rear corners of the door, both strips terminating at their rear ends in hooks engaged with the upper and lower bars; shafts the outer ends of which are mounted in the loops, the inner ends of the shafts being mounted in the door; a first pivot member mounted on the car below the doorway and below the lower bar; a second pivot member mounted on the car below the lower bar and to the rear of the doorway; a straight rigid support, the lower end of which is mounted on the second pivot member, the upper end of which enters within the loop which is adjacentthe rear of the door; a rectangular support embodying primary and secondary arms, the upper end of the primary arm entering within the loop which is adjacent the forward corner of the door, the extremity of the secondary arm being assembled with the first pivot member, the upper ends of both supports 1 being mounted on the shafts, the straight support extending diagonally of the door when the door is opened, the primary arm of the other support extending vertically when the door is opened, and the secondary j arm of the last specified support lying beneath the lower bar when the door is opened. In testimony that I claim the foregoing as my own, I have hereto affixed my signa-' ture in the presence of two witnesses.
